Citrus leaf curl is caused by many different things. Below are the most common causes of curling citrus, along with ways to manage them. Pests Sap-sucking pests like aphids, mites and psyllids feed on citrus leaves by extracting the juices directly from transport tissues. As populations grow, they can cause deformations including curling and cupping in leaves, as well as discoloration.
When you notice your citrus leaves are curling, check their undersides carefully for tiny pests feeding in clusters.
